Slipknot is way too overrated. Their music is lame. I just got sick of listening to them and besides, I don't want to be known as a "maggot".
I copied that list from my YouTube profile which has my favorite bands and forgot to erase "Anal Cunt" from there. I don't think AC makes good music, just stupid music that makes me laugh. Most of those bands still make great music yeah.
Job For A Cowboy, Zimmer's Hole, and Strapping Young Lad are pretty good.
I love instrumental and video game metal. I can only think of the band Powerglove right now, but they are pretty much one of the best.
